Tungsten Electrode Grinders are essential with TIG/GTA welding. Using a Grinder that has been designed and manufactured specifically for tungsten metal is not only a much safer option, they provide more accurate results leading to as many as ten times greater number of arc strikes and giving very d ...

Welding processes can weaken metals by imparting residual stresses into a material, leading to a reduction in corrosion resistance properties. Post Weld Heat Treatment (PWHT) is regularly used to retain the strength of a metal when welding certain materials including high strength stainless steel a ...

Weld Purging is essential when welding tubes and pipes made of reactive metals such as stainless steels, titanium and zirconium. Usually weld zones are confined with purge dams so that the use of argon purge gas is limited and waiting times are reduced. Homemade dams fabricated from paper, sponge ...

Welders are often faced with challenges where high quality stainless steel, duplex and chrome steel welds are required, but where the use of purge gas is not always possible. One solution to this problem is the use of Argweld® Weld Backing Tape™ from Huntingdon Fusion Techniques HFT®. This high te ...

Sealing, stopping and blocking pipes where oils, hydrocarbons and petrochemicals are present can cause major inconveniences with many normal stoppers not being able to handle such conditions. The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® manufactures a Range of Inflatable Rubber ...

Repairs or modifications on pipes can pose challenges, especially where there is liquid present inside, which may result in the expense and danger of system down time and loss of revenue while the system is drained and refilled. To dramatically reduce these costs and speed up the repair or replace ...

Metals that are classed as ‘reactive' (titanium, zirconium and nickel alloys) are sensitive to oxygen when heated. When welding these metals, the oxygen must be purged from the welding zone, down to as low as 10 parts per million (ppm). Weld Purging in this environment will avoid discolouration of ...

Large diameter pipework can cause several challenges, especially when those pipes are manufactured from stainless, duplex and chrome steels, titanium or zirconium. When welding such reactive materials, they need to be purged of oxygen before, during and after welding. It is not cost effective to c ...

Eliminating oxidation and discolouration when welding stainless and duplex steels as well as titanium, zirconium and nickel alloys is crucial in many industries today, because of improving quality control procedures. Welds have to be free from metallurgical defects otherwise they can potentially be ...

The Tungsten Electrode is one of the most important variables involved in TIG welding. Preparing your Tungsten Electrode correctly will help to improve arc starting, arc stability and weld quality. Tungsten Electrode Grinders are a convenient, safer and more accurate way than other methods of gri ...

New power plants are in high demand and several hundred are expected to be built over the next decade. Chromium-molybdenum (chromoly) steel pipe such as P91 is a major construction material for the high pressure piping in these plants and there are particular techniques for welding this pipework to ...

Weld Purging smaller tubes and pipes of different diameters can be challenging, especially when budgets are tight. Often, Welders are left to create their own homemade purging dams out of unsuitable materials such as foam, paper or cardboard. Huntingdon Fusion Techniques HFT® have designed and dev ...

Metallurgically sound and oxide-free welds are a minimum requirement now when welding stainless steel, zirconium, nickel alloys and titanium. Quality control procedures are in place within most industries and welders are no longer able to ‘guess' when their oxygen level is low enough to begin weldi ...

Measuring the oxygen level with a Weld Purge Monitor® before, during and after welding stainless steel is crucial to achieve oxide free, zero colour welds that are metallurgically sound. It is important not to use “oxygen analyzers” or “oxygen safety monitors” as they are calibrated for accuracy on ...

During petrochemical operations, where hydrocarbons are present in liquid or gas form, inflatable stoppers are often used for various applications such as debris stopping, leak testing, low-pressure hydrostatic tests, blocking the release of hydrocarbon gases and a variety of plumbing operations. ...
